Solve the equation by factoring.
25d3 – 36d = 0
2 answers:
Answer:
-6/5, 0, 6/5.
Step-by-step explanation:
25d3 – 36d = 0
The GCF is d so we have:
d(25d^2 - 36) = 0
d = 0 is one solution, and:
25d^2 - 36 = 0
25d^2 = 36
d^2 = 36/25
d = +/- 6/5
d = -6/5, 6/5.
Answer:
-6/5, 0, 6/5
Step-by-step explanation:
First factor out the d and you are left with d(25d^2-36)=0 (a+b)(a-b) = a^2-b^2 Using that principle you can then simplify further by factoring it into d(5d+6)(5d-6)=0 Then just solve to get the answers.
